Critical Path Method for CE

I was wondering which source would you recommend to study CPM. I took CE a couple of months ago (failed). In the exam there are several questions related on how to manage a construction schedule using Critical Path Method.

I appreciate any advise or information about a book or video which can help me tackle this subject.

I am also waiting on the Pluralsight website for CE, hopefully is out before I take my exam on March.
